SYMPTOMS

When you are using an array of 30 disks, Disk Administrator can access, partition, format, and assign drive letters to any drive in the system. With Microsoft Cluster Server installed, you can use any disk provided that the disk has a device number in the range of from 0 to 25.

CAUSE

This limitation is caused by a hard-coded value for the disk resource DLL, which should be set to maximum disks (which equates to 100).
